+* Renesas H8/300 16bit timer
+
+The 16bit timer is a 16bit timer/counter with configurable clock inputs and
+programmable compare match.
+
+Required Properties:
+
+  - compatible: must contain "renesas,16bit-timer"
+  - reg: base address and length of the registers block for the timer module.
+  - interrupts: interrupt-specifier for the timer, IMIA
+  - clocks: a list of phandle, one for each entry in clock-names.
+  - clock-names: must contain "peripheral_clk" for the functional clock.
+  - renesas,channel: timer channel number.
+
+Example:
+
+       timer16: timer@ffff68 {
+               compatible = "reneas,16bit-timer";
+               reg = <0xffff68 8>, <0xffff60 8>;
+               interrupts = <24>;
+               renesas,channel = <0>;
+               clocks = <&pclk>;
+               clock-names = "peripheral_clk";
+       };

+* Renesas H8/300 8bit timer
+
+The 8bit timer is a 8bit timer/counter with configurable clock inputs and
+programmable compare match.
+
+This implement only supported cascade mode.
+
+Required Properties:
+
+  - compatible: must contain "renesas,8bit-timer"
+  - reg: base address and length of the registers block for the timer module.
+  - interrupts: interrupt-specifier for the timer, CMIA and TOVI
+  - clocks: a list of phandle, one for each entry in clock-names.
+  - clock-names: must contain "fck" for the functional clock.
+
+Example:
+
+       timer8_0: timer@ffff80 {
+               compatible = "renesas,8bit-timer";
+               reg = <0xffff80 10>;

+This implementation support only cascade mode.
+
+Required Properties:
+
+  - compatible: must contain "renesas,tpu"
+  - reg: base address and length of the registers block in 2 channel.
+  - clocks: a list of phandle, one for each entry in clock-names.
